Application led May 22,

To `ZZ whom. 'it' 'muy concern f Be it known that I, STANLEY W. Nici-roi;- son` a citizen of the United States of America, residing at Toledo,y in the l county of Lucas and State of Ohio, have invented certainnew and useful improvements in Tindow-Control Mechanism, of vwhich the following is a specification7 reference being had therein to the accompanying drawings.

This intention relates to window control mechanisn'i and relates moreparticularly to control mechanisms for the sliding windows ofy vehicles.

The invention consists in the structural features and arrangement of partshe'reiir after fully described and illustrated in the accompanying drawings wherein Figure 1 is an interior view of a motor vehicle door eqnipp'edivwith thef improved control mechanism;

Figure 2 is a cross section on line 2-,2 of Figure l; v i

VFigure 3 is a fragmentary perspective view of the actuating and latch elements for said mechanism.

Iny these views the reference character A- designates an automobile door formed in its upper portion with a` window opening B provided with a vertically sliding;l closure C having'the nature of a glass plate. In open ing` the windowy saidplate is adapted to be lowered .into a well or chamber D formed F is, a

said arm being pivoted at one. end upon a npright A of the door, as indicated at F,

and carrying at its other orfree end a rollerl F2 which is caused toV bear constantly upon the lower edge of the closure C by a coiled said` chisnrey adjacent the lower edge of the i latter. Said rod is upwardly extended a snticient distance to render the handle H zazcessihle, even when the closure is in its lowermost position. lt is desired'toutilize the rod H to control latching of the plate C, as well as to actnate vertical movement of the latter and to this end said rod is rotatively engaged with the closure. Y Thus the channel member l which embracesthe bot- 1922. SeratNO. 5621870.

tom edge of the plate C (as is common practice) is formed at one end with a laterally extended tongue l which is terminally fas iiened to form abearing l2 wherein the lower end portion oiithe rod H is journaled. llilithin thewell i) there is secured to the upright A', by screws lis, a vertically elongated latch plate l having' an edge portion extendingy in back ofthe rod H and formedrwith series of notches J. The rodl'l. projects slightly below the journal bearing I2 and is'termi- `nally lient and iiattened, as indicated at l,`

Cty

C, as shown in full lines in Figure 2 and in l y dash lines in the same figure is indicated the position ofisaid handle corresponding to the released position of the latch element K also shown in dash lirios).l It is preferred to vertically zQ'roove the member A within the well D in back of the notched edge portion of the plate J', as shown at M, to provide/the necessary clearance for rocking and vertical travel of the element K;

Hthin the window opening)` B a tubular metal trim stick N is secured to the upright A and it is preferred to locate the control rod H' within said trim stick7 the latter bew ing`V vertically slotted, as indicated at N', to permit the handle H to project and to nndergo the necessary vertical rand annular movements. Preferably the edges of said trim stick, marginal to the slotI N', are beaded interiorly of the trim sticle as indicated at N2, for the purpose of reinforcing the trim stick. Asis best seen in Figure 2 the slotted edge portion of the plate ,l lies directlyV beneathl the trim stick \T in order to establish the necessary coaction with the latch element K. Said figure also best discloses the employment of the plate l as ay seat or backing: for the felt slideway (l f,

which marginally engages the plate C.

One yof the main advantages which is sei cured by the described4 construction is the complete concealment of the latch means within the `well D, as well as a substantial concealment of the controlfrod H within thev tubular trim stick N. The described latch means, ivhile ot a very simple nature, suliiccs to securely maintain a sliding closure in any ot a large number of selective positions of adjustment.

llihat I claim as my invention is zn 1. ln a WindouT control mechanism the combination with a sliding' Window closure and a chamber receiving said closure in Window opening positions thereof, oi' a latch plate extending` Within said chamber in the direction ot movement of said closure, a coaeting` latch element and av rotative control r' ember tor said latch element project- .ing into the WindenT openingin all positions oftl said closure.

2. In a Window control mechanism the combination with a sliding,` closure for a window opening, of a. chamber receiving said closure in the Windev7 opening positions thereof, an elongated latch plate extending Within said chamber in the direction of movement or" said closure, a coacting` rotative latch element and control means for said element accessible Within the Windovv openingin all positions of the closure.

3. In a Window control mechanism the combination with a sliding closure for a window opening, of a. chamber receiving said closure in the .vindovv openingpositions thereo t, an elongated latch plate eX- tcnd-ing Within said chamber in the direction of movement ot the Window member, a coacting rotative latch element carried by said closure and a. control rod mounted upon said closure tor actuating the same projecting into said ivindoiv opening in all positions of the closure and rotative to actuate said latch element.

il. ln a Window control mechanism a slidable window member, ar chamber receiving said member in its open positions, a latch member within said chamber elongated in the direction oit travel ot the Window member, a latch element upon the ivindoiv member coacting ivith said latch member, and a rod mounted upon the Windov.' member controllingv sliding' thereof and rockable to additionallyy control said latch element.

5. In a vindoiv control mechanism, a vertically slid-able window closure, a vertically elone'ated latch member downwardly extend-ing' trom the Window opening, a control rod rotatably mounted upon the closure, and a latch clement carried by said closure adjacent the loiver edge thereof: coactin with the elongated latch member to hold the closure adjusted and controlled rotatively by said rod.

6. In a Window control mechanism, the combination with a slidable Window membei', a rod rotatively extending upon said member in the direction of travel thereof, a latch element upon one end portion ot said rod, coacting` stationary latch means, and a handle. upon the other end portion ot said rod controlling travel of said ivindoiv member by subjection ot the rod to longitudinal stress, and controllingl said latch element through rotation ot the rod.

7. ln a Window control mechanism, a sl-idable ivindoiv member, a. chamber receiving' id member in open positions thereof, a tir-:ed latch member located substantially in its entirety .vithin said chamber, a coacting latch element carried by the nf'indoiv member, and amembcr carried ly the findow member actuatiing` sliding; thereo't and rotative to control said latch element.

S. ln a ivindou7 control mechanism, a slidable Windenv member, a control rod tatively mounted upon said ivindov.v member and extending` parallel to the direction oi travel thereof, and an actuating` handle and latch element mounted tast respectively upon the extremities of said rod.

9. ln a ivindoiv control mechanism` the combination with a sliding` closure iter a ivindovv opening, of a chamber receiving;` said closure .in the window opening` position thereot, an elongated latch plate extending; within said chamber in the direction ot movement ot said closure, a coactingl latch clement rotative upon an anis parallel to the direction ot moven'ient ot said closure, and control means Jfor said rotative element accessible within the ivindoiv opening in all positions ot the `losure.

l0. ln a Window control mechanism, the

combination with a. slidable ivindoiv member, ot a control rod extending` upon said member in the direction ol travel thereof, said rod having a transversely bent portion at oneI extremity 'forming a latch elemort and a transversely bent portion at the other extremity and spaced longitudinally ot said rod from said first-mentioned transverselj.,v bent portion and forming` a handle, and s .ationary latch means engageable by said first-iuentioned transversely bent portion.

ln testimony whereof l alix my signature. i
